Mind the Keys!

Weekend project

This is a Weekend project made with Tokymaker, an intuitive way for youngs and adults to learn the fundamentals of electronics, programming and solve problems creatively. If you don’t know what is it yet, follow the link and come back later!

Solution

We are going to devise a system that keeps the keys to us when entering the house and that we are advised to take them when leaving. Thanks Tokymaker!

We will use a distance sensor that detects our presence crossing the main door of the house. At that moment, with the help of a servo motor, we will extend a robotic arm with the keys, so that we can take them. We will also show on the screen a warning message: “The keys!”

Material

Learn to code your own prototypes using the simple visual coding interface and just one finger and program it without installing software or connecting cables. Understand the principles os electronics connecting in the most intuitive way, a large variety of sensors and actuators.
